Interactive Matter Review
The teachers acted out the states of matter. Which of
these shows a good model for a liquid?
The teachers here are staying close, but
each atom (teacher) stays in one place
and rocks. This would be a good model
for a solid. The atoms of a liquid are able
to glide around each other.
Try again
Excellent! These atoms (teachers) are
moving around each other while
staying close. They make a good
model of a liquid.

The teachers here are staying close, but
each atom (teacher) stays in one place
and rocks. This would be a good model
for a solid. The atoms of a liquid are able
to glide around each other.
Try again
These atoms (teachers) are moving
around each other, but they stay far
away and do not touch. This would be a
good model for a gas.

Which object below is the same state of
matter as this book?
The water in the fountain is able to
change its shape as it moves into
different places. The book keeps its
shape and volume.
Try again
Yes! The chair keeps its shape and
volume. The book and the chair are
both solids.
Next question
The steam spreads out as it rises from
the cup. It has no definite shape or
volume. The book keeps its shape and
volume.

Which of the measurements below
could be the length of the stapler?
A. 7 centimeters
B. 17 centimeters
C. 47 centimeters
D. 7 meters
Not quite. A crayon is about 7
centimeters.
Try again
Correct! A stapler might be about 17
centimeters long.
Next question
Not likely. Your science book is only 30
centimeters long. The stapler would not be
longer than your science book.
Try again
No. Most cars are less than 7 meters. A
stapler would not be that long!

From this picture, which physical
property can NOT be observed?
A. furry B. brown
C. bigger than a D. soft
rubber duckie
No. The bear is furry – you can see
the fur in the picture.
Try again
No. The bear is brown – you can see
the fur in the picture.
Try again
No. The bear is larger than the rubber
duckie. You can see that in the picture.
Try again
Yes. The bear may be soft, but you
cannot feel that in the picture.
Next question
Some students brought examples of
physical changes to class. Which of these
is NOT a physical change?
Correct! Burning creates a chemical
change. The logs will be gone, leaving
ashes behind.
Next question
No. Sawing a board is a physical
change. There are now two smaller
pieces of wood.
Try again
No. Cutting paper is a physical change.
There are now two smaller pieces of
paper.
Try again
No. A melting popsicle is a physical
change. The solid popsicle is becoming
a liquid. It is still made of juice and
water.
Try again
Which one of these is NOT a property
of a solid?
A. has a definite shape
B. has a definite volume
C. takes the shape of its container
D. atoms are tightly packed
No. That IS a property of a solid. A solid has
a definite shape. Read your question stem.
Try again
No. That IS a property of a solid. A solid has
a definite volume. Read your question stem.
40 mL 40 mL
30 mL 30 mL
20 mL 20 mL
10 mL 10 mL
Try again
Correct! A solid does not take the shape of
its container because it has its own shape.
Next question
No. Having tightly packed atoms IS a
property of solids. Read your question stem.

Which object below would most likely have
a mass of one kilogram?
No. An apple would have a mass of about
100 grams. A kilogram is equal to 1,000
grams. Its mass is too small.
Try again
Yes. A large book, such as a text book
would have a mass close to one kilogram.
Next question
No. An elephant’s mass could be several
hundred kilograms. Its mass is far too big.
Try again
No. A paperclip has a mass near one gram. It
takes 1,000 grams to equal the mass of one
kilogram. The paperclip’s mass is far too
small.
Try again
Which of these is NOT an example of a
chemical change?
Correct! The snowman is melting, changing
from a solid to a liquid. That is only a
physical change.
Next question
No. Baking a cake is a chemical change.
After baking, the eggs, flour, and sugar
have become a cake. You cannot get those
ingredients separated.
Try again
No. Mixing chemicals can cause a chemical
change. The solid baking soda powder mixed
with liquid vinegar has created carbon
dioxide. That gas is newly made.
Try again
No. Burning causes a chemical change.
The match is becoming ash and smoky
gases.
Try again
Which one of these liquids would be
measured in liters?
Perfume
No. A baby bottle would hold about
300 mL of milk. It takes 1,000 milliliters
to equal one liter.
Try again
No. A dropper would hold a few
milliliters of medicine. It takes 1,000
milliliters to equal one liter.
Try again
No. A perfume bottle would hold a
about 100 milliliters of perfume. It
takes 1,000 milliliters to equal one
liter.
Try again
Yes! The pool would hold several hundred
liters of water.
Next question
Below are four statements about measuring.
Which one of the statements is NOT true?
A. The mass of an object can be found
by using a balance.
B. A milliliter is equal to 1,000 liters.
C. The volume of a liquid can be
measured with a graduated cylinder.
D. 1,000 grams are equal to one kilogram.
The mass of an object CAN be found
by using a balance. That is a TRUE
statement.
Try again
Correct. A milliliter is NOT equal to
1,000 liters. It is smaller. It takes 1,000
milliliters to equal one liter.
Next
No. The volume of a liquid CAN be measured
with a graduated cylinder. That is a TRUE
